I'm currently developing an android application where I'm using a navigation drawer as well as the swipe gesture using viewPager to traverse through fragments.
Basically, I want the user to be able to select pages (fragments) using the navigation drawer and be able to swipe to the next page (fragment).
My problem right now is that they overlap. The swipe gesture works as expected but when I select another page on the nav drawer they underlying page doesn't disappear. I need someway to "refresh" each fragment.
Here is my code in the MainActivity.java page
package com.example.home.cloud;

The trouble is that you're displaying your fragments in two different ways. Your displayView() method is creating new fragments and displaying them, rather than showing the ones which are already loaded in the ViewPager. To fix this, you need displayView() to instead set your ViewPager position.
private void displayView(int position) {
mPager.setCurrentItem(position);
getSupportActionBar().setTitle(mPagerAdapter.getPageTitle(position));
}

i am begineer in android development , i would like to configure hardware backbutton to go back to previous fragment and the fragment titles should also change according to the current fragment ,

fragmentTransaction.replace(R.id.container_body, fragment);
fragmentTransaction.addToBackStack(null).commit();
// set the toolbar title
getSupportActionBar().setTitle(title);
}
}
}
plz hel me in fixing this .
You are adding the transaction to the backstack, so all you should need in order to get back to the previous one should be:
FragmentManager fragmentManager = getSupportFragmentManager();
fragmentManager.popBackstack(null, 0);
You may also consider adding an id for each fragment and passing it when calling
fragmentTransaction.addToBackStack(null).commit();
instead of the null. This way, you will be able to do this:
fragmentTransaction.addToBackStack(myFragmentId).commit();
//Later on...
FragmentManager fragmentManager = getSupportFragmentManager();
fragmentManager.popBackstack(myFragmentId, 0);
To go back to a specific fragment, not just the last one :-)
every time when you add a fragment just add addToBackStack() method before commit and then in your activity on back pressed try this
public void onBackPressed() {
int count = getSupportFragmentManager().getBackStackEntryCount();
if (count == 1) {
goToExitApplication(
getResources().getString(R.string.close_app), true);
} else {
String title = getSupportFragmentManager().getBackStackEntryAt(count - 2).getName();
getSupportFragmentManager().popBackStack();
getSupportActionBar().setTitle(title);
}
}
I have used this in my code:
#Override
public void onBackPressed() {
if (getSupportFragmentManager().getBackStackEntryCount() > 0 ){
getSupportFragmentManager().popBackStack();
} else {
super.onBackPressed();
}
}
To push the Fragment I used:
MyFragment_Items myf = new MyFragment_Items();
transaction = getSupportFragmentManager().beginTransaction();
transaction.replace(R.id.container_layout, myf);
transaction.addToBackStack(null);
transaction.commit();
I pushed the fragment here and popped it back onBackPressed.
It will Surely work for you If there is any Fragment on the back stack of current fragment , popBackStackImmediate() works..
#Override
public void onBackPressed() {
if(getFragmentManager().getBackStackEntryCount() > 0){
getFragmentManager().popBackStackImmediate();
}
else{
super.onBackPressed();
}
}
I want to change the Action Bar title from fragment to fragment..
example loginfragment to registerfragment..
i have button at loginfragment that will redirect to register fragment..
case R.id.textSignup:
FragmentManager fragmentManager = getFragmentManager();
fragmentManager.beginTransaction()
.replace(R.id.container, RegisterFragment.newInstance())
.commit();
break;
and i add this code in my registerfragment
public static RegisterFragment newInstance() {
RegisterFragment fragment = new RegisterFragment();
return fragment;
}
public RegisterFragment () {
}
#Override
public void onAttach(Activity activity) {
super.onAttach(activity);
((MainActivity) activity).onSectionAttached(3);
}
then here is the MainActivity
public void onSectionAttached(int number) {
switch (number) {
case 1:
mTitle = getString(R.string.title_home);
break;
case 2:
mTitle = getString(R.string.title_login);
break;
case 3:
mTitle = getString(R.string.title_register);
break;
}
}
#SuppressWarnings("deprecation")
public void restoreActionBar() {
ActionBar actionBar = getSupportActionBar();
actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_STANDARD);
actionBar.setDisplayShowTitleEnabled(true);
actionBar.setTitle(mTitle);
}
the problem is the register title is not displaying even i add onSectionAttached(3) in the registerfragment..

thanks

i.e bcoz you not calling restoreActionBar() function anywhere in your code.
you can change actionbar Title as you navigate from fragment to fragment by like this aswell in onCreateView()of each Fragment.
ActionBar actionBar = getActivity().getActionBar();
actionBar.setTitle("Your title");
The simplest way is to call
getActivity().setTitle(your_title)
in the onCreate() method in all of your fragments
I am working on this application that has a viewPager and a few swipeable fragments in its MainActivity. Today I implemented navigation drawer but I do not know how to control which fragment is shown from drawer`s DrawerItemClickListener class. Is there a solution or I was just moving in a wrong direction and have to change the way navigation drawer is implemented?
Tutorial suggests to use the getFragmentManager method which does not work for me.
Thanks.
Here is DrawerItemClickListener class:
package com.freestylers.druskischool;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;
import android.util.Log;
import android.view.View;
import android.widget.ListView;
import android.widget.AdapterView;
public class DrawerItemClickListener implements ListView.OnItemClickListener
{
public int FragmentNumber;
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long
id) {
selectItem(position);
}
private void selectItem(int position) {
Fragment fragment = null;
switch (position) {
case 0:
fragment = new StartFragment();
FragmentNumber=0;
break;
case 1:
fragment = new MesFragment();
FragmentNumber=1;
break;
case 2:
fragment = new NaujienosFragment();
FragmentNumber=2;
break;
case 3:
fragment = new InstruktoriaiFragment();
FragmentNumber=3;
break;
case 4:
fragment = new MetodikaFragment();
FragmentNumber=4;
break;
case 5:
fragment = new GalerijaFragment();
FragmentNumber=5;
break;
case 6:
fragment = new InstruktoriaiFragment();
FragmentNumber=6;
break;
case 7:
fragment = new AtsiliepimaiFragment();
FragmentNumber=7;
break;
case 8:
fragment = new DrufunparkFragment();
FragmentNumber=8;
break;
case 9:
FragmentNumber=9;
fragment = new KontaktaiFragment();
break;
default:
break;
}
if (fragment != null) {
//tutorial suggests this code:
FragmentManager fragmentManager = getFragmentManager();
fragmentManager.beginTransaction().replace(R.id.content_frame, fragment).commit();
mDrawerList.setItemChecked(position, true);
mDrawerList.setSelection(position);
getActionBar().setTitle(mNavigationDrawerItemTitles[position]);

I figured out my mistake, it all has to be inside MainActivity.java, DrawerItemClickListener is an inner class.
Still have not found a way to navigate between swipeable fragments from the navDrawer, probably it is impossible.
Last week I started developing on android. I'm making an app for the gym where I train. I've made the main functions so far but i'm stuck trying to add the animation when the navigation drawer is opened or closed. Right now the navigation drawer is fully functional but the arrow doesn't animate as you can see from the picture:

I hope you can help me. Thanks in advance
You need to sync the drawer:
ActionBarDrawerToggle drawerToggle = new ActionBarDrawerToggle(<context>, drawerLayout, 0, 0, 0);
drawerLayout.setDrawerListener(drawerToggle);
drawerToggle.syncState();
Here I have a code where you can swipe the tab menus, but I want that after a swipe another activity is opened, for example Simmering.class.
I think this should go with an intent, but how or where should I put it.
Here is the code:
import java.util.Locale;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentActivity;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentPagerAdapter;
import android.support.v4.app.NavUtils;
import android.support.v4.view.ViewPager;
import android.view.Gravity;
import android.view.LayoutInflater;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.view.ViewGroup;
import android.widget.TextView;
#SuppressWarnings("unused")
public class MainActivity extends FragmentActivity {
/**

* fragments for each of the sections. We use a
* {#link android.support.v4.app.FragmentPagerAdapter} derivative, which
* will keep every loaded fragment in memory. If this becomes too memory
* intensive, it may be best to switch to a
* {#link android.support.v4.app.FragmentStatePagerAdapter}.
*/
SectionsPagerAdapter mSectionsPagerAdapter;
/**
* The {#link ViewPager} that will host the section contents.
*/
ViewPager mViewPager;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// Create the adapter that will return a fragment for each of the three
// primary sections of the app.
mSectionsPagerAdapter = new SectionsPagerAdapter(getSupportFragmentManager());
// Set up the ViewPager with the sections adapter.
mViewPager = (ViewPager) findViewById(R.id.pager);
mViewPager.setAdapter(mSectionsPagerAdapter);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
/**
* A {#link FragmentPagerAdapter} that returns a fragment corresponding to
* one of the sections/tabs/pages.
*/
public class SectionsPagerAdapter extends FragmentPagerAdapter {
public SectionsPagerAdapter(FragmentManager fm) {
super(fm);
}
#Override
public Fragment getItem(int position) {
// getItem is called to instantiate the fragment for the given page.
// Return a DummySectionFragment (defined as a static inner class
// below) with the page number as its lone argument.
Fragment fragment = new DummySectionFragment();
Bundle args = new Bundle();
args.putInt(DummySectionFragment.ARG_SECTION_NUMBER, position + 1);
fragment.setArguments(args);
return fragment;
}
#Override
public int getCount() {
// Show 3 total pages.
return 4;
}
#Override
public CharSequence getPageTitle(int position) {
Locale l = Locale.getDefault();
switch (position) {
case 0:
return getString(R.string.title_section1).toUpperCase(l);
case 1:
return getString(R.string.title_section2).toUpperCase(l);
case 2:
return getString(R.string.title_section3).toUpperCase(l);
case 3:
return getString(R.string.title_section4).toUpperCase(l);
}
return null;
}
}
/**

* displays dummy text.
*/
public static class DummySectionFragment extends Fragment {
/**
* The fragment argument representing the section number for this
* fragment.
*/
public static final String ARG_SECTION_NUMBER = "section_number";
public DummySectionFragment() {
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_main_dummy, container, false);

dummyTextView.setText(Integer.toString(getArguments().getInt(ARG_SECTION_NUMBER)));

Try adding below code in onCreateView method of your fragment class. check for the position after which you want to start new activity. And in it call the startActivity method.
Intent intent = new Intent(getApplicationContext(), Simmering.class);
getApplicationContext().startActivity(intent);
Do you know, that starting new activity after swipe hide page you're swiping to? If your answer is yes, you can use ViewPager's onPageChangeListener. It's methods are invoked when page is changed/updated etc. Usage is following:
mViewPager.setOnPageChangeListener(new OnPageChangeListener() {
#Override
public void onPageSelected(int index) {
// TODO Auto-generated method stub
}
#Override
public void onPageScrolled(int arg0, float arg1, int arg2) {
// TODO Auto-generated method stub
}
#Override
public void onPageScrollStateChanged(int arg0) {
// TODO Auto-generated method stub
}
})
i already found an option to achieve what i wanted, here is the code:
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentActivity;

#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
viewPager= (ViewPager) findViewById(R.id.pager);
FragmentManager fragmentManager=getSupportFragmentManager();
viewPager.setAdapter(new MyAdapter(fragmentManager));
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
// action with ID action_refresh was selected
case R.id.action_refresh:
Toast.makeText(this, R.string.refresh_clicked, Toast.LENGTH_SHORT).show();
break;
// action with ID action_settings was selected
case R.id.action_settings:
Toast.makeText(this, R.string.settings_clicked, Toast.LENGTH_SHORT).show();
break;
default:
break;
}
return true;
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
}
class MyAdapter extends FragmentStatePagerAdapter
{
public MyAdapter(FragmentManager fm) {
super(fm);
}
#Override
public Fragment getItem(int i) {
Fragment fragment=null;
switch(i){
case 0: fragment = new Home(); break;

case 9: fragment = new Bregenz(); break;
case 10: fragment = new Kufstein(); break;
case 11: fragment = new Bratislava(); break;
}
return fragment;
}
#Override

return 12;
}
#Override
